based on what I have learned from others, the Daytona bearing support is not needed unless it comes with the center section already. The 31 spline axles are a good idea at your power level. Of coarse that requires a different carrier. I don't know what kind of case you have but even the stock cases should hold 450 horse.
As far as the small bearing ends go, that's up to you. Aftermarket axles are made in 31 spline and accept stock small bearing, Moser makes them this way. In addition your brakes are already setup for the small bearing ends.
I don't know about the housing but I have never seen any one bust a housing. I have seen the spring perches crack at the welds.
